Acute cholecystitis 為何用抗生素？

Q: When is it necessary to give antibiotics for acute cholecystitis?

A: The rationale for the use of antibiotics and the choice of which antibiotic to use is based on the results of bile cultures from patients with acute cholecystitis. The guidelines of the Infectious Diseases Society of America recommend that antimicrobial therapy be instituted if infection is suspected on the basis of laboratory and clinical findings :

1. more than 12,500 white cells per cubic millimeter
2. body temperature of more than 38.5°C and
3. radiographic findings (e.g., air in the gallbladder or gallbladder wall)
